Ford - Explorer :: 2004 - No Heat - No Vacuum Signal To Heater Valve?
I have an '04 Explorer Limited and lately only blows cold air. I've read about the blend door motors but it's been too cold in MI to want to do much--so the truck sits.
When I was troubleshooting the problem I found that I'm not getting any vacuum signal to the heater valve in the coolant line. Before I contemplate removing the console & doing surgery on my dash I'd like to know for sure what position the valve should be in when heat is called for.
All the other vacuum actuators seem to be working normally and there's no disconnected hoses under the dash; and no leaks. Coolant reservoir is full.
Ford - Explorer :: 2004 - No Heat / Not Getting Vacuum To Call For Coolant To Enter Heater Core
I bought a 04 explorer with a bad thermostat which led to a bad head gasket, fixed that and managed to not have to buy the special tools or time it , but now that its running I don't have any heat. I have complete service records on this vehicle and there was never a complaint of the heater not working. The a/c works and the heat will adjust the a/c temp, but no heat. In trouble shooting it I found that I am not getting vacuum to call for the coolant to enter the heater core. When I apply suction to it, it will send the coolant. Even though I wasn't getting the clicking noise, I pulled the blend door actuator and it looks surprisingly good (not looking forward to putting it back in). Where to look next?

I have a 03 explorer and when on defrost if I turn the temp to hot it changes from defrost to heat, also if i lower the temp setting a little it goes back to defrost,this has manual heater control and I replace the control head and did not solve this issue.

My exlporer heat and A/C system has been making "ticking or flapping" noises for sometime. So, to make it stop I would turn fan to full blast and it would stop and the heater would function fine after that. Last week we hasd a warm spell and I switched to A/C (going through the same process to stop the noise). All was well until I tried to switch back to heat after the warm spell, and now I get nothing but cold air. The noise will only stop when I turn the temp dial to the cold side, but either way, all I get is cold air. Is this something I can fix, and if not what am I looking at for repair cost? I'm freezing!!!

My 2010 Ford Explorer experienced a radiator leak between the radiator and the plastic tank on the top, so I replaced that, we were still not experiencing any heat while driving it. I watched a couple of videos on how to "burp" the system, to no avail.
Next I replaced the thermostat, and "burped" it again, still no heat, so I drained and flushed the system yet again and still no heat. What else is there to check? I have the Haynes manual and did the flush and fill the way the book said and still have no heat I am about to lose my mind.
The blend doors sound like they are opening. They are not clicking like they are broken.
The heater is on full the entire time, I have not rotated the dial since I started this.
I unplugged one of the hoses on the heater core and blew into it, the hose was bone dry and I blew into the end of the hose and fluid came out of the cabin side metal tube. I also plugged a water hose into the tube and ran water through it to make sure it wasn't clogged, it is not. Front and rear heater cores.
Here is everything thing I have done from the start:
- Replaced Radiator.
- Replaced Thermostat.
- Drain and flush and re-service.
- Checked for leaks out of the water pump weep hole (none) and operation of pump, the upper hose gets hot and I feel water go through it when the thermostat opens.
- Check the radiator cap for pressure, it opens at 20psi and hold between 17-19psi. Replaced radiator cap anyway.
- Removed supply hose and ran coolant to purge trapped air.
- Ran water through the supply and return hoses on the heater core. On the front and rear.Check operation of heater control valve, works.
- Turned vehicle on while watching the exhaust pipe, a small amount of water on initial start up in the morning but no smoke.
Problems still occurring:
-Drive vehicle it over heats but returns to normal at idle I also get the coolant light that extinguishes when the car returns to idle. Even though it says its overheating the car has not pushed coolant into the expansion tank.
- The car will not take any more coolant, and only overheats after the fan comes on. And still no heat.
Should add, 4.0L engine, no oil in water after flush and the engine oil looks like engine oil not milky. Next step was a water pump???
Ford - Explorer :: 2003 XLT - Heat / AC System Is Stuck In Defrost
I just picked up another 2003 XLT and I'll be taking it in for inspection on Monday. Hoping it will pass easily, but there are a couple issues I'd like to address before going in there.
First and foremost, the heat/AC system is stuck in defrost. It will turn off when the selector is moved to the OFF position, but any other position just makes the air blow out the top of the dash. I did do some research on this beforehand (the seller made me aware of it) and I first looked at the actuator. When moving between positions, the actuator does not move at all. It does appear to be connected to the vent door's arm but there's no movement when going around the dial. I do hear what seems to be a relay kick on or off as I go through the different modes, but that's it. Does this point more towards a vacuum issue?
Second, and less significant...the self-dimming rear view mirror doesn't dim. It doesn't even power on. Where might the connection go for that mirror? Would be handy to have for night driving, but not that big of a deal if it's not functioning.
I'm also going to have to get the tailpipe mounted...seems it came off at some point and the seller asked me today if I wanted it. Uh...yeah, I'm gonna need that to pass inspection!
I am liking it so far. Runs well, rides well...I will be enjoying this one as well.
Ford - Explorer :: 2003 - Clicking Noise - Heat Does Not Work
I just purchased a 2003 Explorer and the heat doesn't work. When I turn the fan to hot it makes a clicking noise~as I've been searching around these forums it sounds like it the blend door actuator?? Does this sound right?

Started up the 2002 EXP today and thought the fuel pump was failing. Get a consistent thump every 1 second. Later today i looked and noted the noise is coming from drivers rear fender well (i think). I took off the small plastic cover of the rear blower motor and thought it was in that area. Disconnected the motor and still thumps. Disconnected the blower motor resistor block and still thumps. Looked at the overhead consol and the rear blower was on HI. Turned the blower down and as you reduce speed the noise volume is lower. Turned the switch off and i thought the noise was gone. Pulled the cup holder above the fender well looking for a relay or something in that area. I cant isolate the noise but seems to be real close to that area. Later i heard the noise, very faint, and the blower switch was off. Turned it to 1-2-3 and it gets much louder. Turned it off and very slight noise. What am i looking for? My hearing is not accurate enough to find it.
View 2 RepliesFord - Explorer :: Door Ajar Goes Away / Relay Steadily Clicking When Turn On Rear Heat
2 strange things my 03-04 explorer is doing.
(1) it keeps telling me I have a door ajar. the weird part is, if I turn the interior/dash lights off, it goes away, even after I turn them off and back on. Also, after doing that to get the message to go away, when I turn on my rear defrost, the message comes back on. I've sprayed the heck out every door with WD-40 to try and loosen a stuck switch.
(2) occasionally, when I turn on the rear heat, you can hear, what sounds like a relay, steadily clicking in the rear drivers side of the cargo area.
What either of the two issues might be?
Ford - Explorer :: 2004 Explorer - Transmission Seal Blowing When Under A Heavy Load
I'm in a situation where I may be having to tow my 3500# boat/trailer with my '04 Explorer 4WD (this is well within the max tow limit, per the manual). I have the 4.0L with the 5 spd auto tranny and 3.73ls gears. I've towed the boat a handful of times with this vehicle and had a good experience every time. Now I'm looking at this being my primary towing vehicle, towing once or twice a month in the summer. The car only has 48000 miles on the ticker and is in pristine condition, so mechanically it's sound.
I asked my mechanic what he thought of this arrangement and he hates the Explorers, so he's giving a biased response. Have any of you towed something on a somewhat regular basis with this, or a similar, vehicle? Any issues? My mechanic keeps going on about the transmission seal blowing when under a heavy load.
Ford F-150 (2004-2008) :: Slow To Heat Up?
If I start it on a cold morning and leave it idling for 20 minutes it will finish warming up within a mile or two. But if I just take off driving right after I start the engine, it takes close to 10 minutes to finally start warming the cab up. Is this normal for these trucks or is it possible the thermostat needs to be changed?
I found this service bulletin, which matches a symptom my truck has. Is it possible the rolling fan at cold idle could be keeping the engine from warming up as quickly?

In winter now and stops blowing hot air after 30-40min of driving. Turn system off for 15min. and will blow hot again. Had new A/C compressor and a/c clutch installed back in summer.???
Ford 6.0L Power Stroke Diesel :: 2004 - Heat Up During Idle
I have a 2004 Excursion Limited with a 6.0 PSD. Recently I have noticed my temp, I have a Scan Gauge II, slowly climbing when I am idling. On the highway it runs anywhere from 175-205 depending on time of year and load I'm pulling. Lately I have noticed it starting to climb while sitting in a parking lot at idle after coming off a steady speed run. Temp goes from about 175 up to about 205 just at idle. It is a slow creep up not a dramatic change. I have checked my coolant levels and it is full. I have made sure the front of the radiator is clear.

I have a 1998 f150 4.6 that has a problem with the heating system. It's blowing out a little warm, but "far" from what it should be. ( on a scale from 1-10, I'd rate it about a 3) I am puzzled because I flushed the radiator, changed the thermostat, and there a no signs of heater core leaks inside,hose leaks on firewall, or radiator/water smell present. I don't know if this has anything to do with it, but I did notice the top radiator hose was hot, but not the bottom. I don't know what else to look for.
